Our avian conservation program focuses on the monitoring and protection of bird-friendly habitat on the Osa Peninsula, Costa Rica. Our projects include scientific investigation of endemic and endangered bird species, monitoring of the abundance and long-term health of both resident and migratory bird populations, and activities and partnerships promoting bird conservation throughout the Americas.

Costa Rica’s south Pacific coast is home to over 400 species of birds. About a dozen of these species are endemic and restricted to the Osa region and adjacent Panama. These include at least five species of conservation concern which inhabit the lush tropical forests and coastal mangroves of the Osa Peninsula.

  • Yellow-billed Cotinga (Carpodectes antoniae)
  • Black-cheeked Ant-Tanager (Habia atrimaxillaris)
  • Mangrove Hummingbird (Amazilia boucardi)
  • Turquoise Cotinga (Cotinga ridgwayi)
  • Baird’s Trogon (Trogon bairdii)

Osa also provides important wintering habitat for many North American migratory breeding birds including the Olive-sided flycatcher (Contopus cooperi), Wood thrush (Hylocichla mustelina), Golden-winged warbler (Vermivora chrysoptera), Kentucky warbler (Oporornis formosus), Prothonotary warbler (Protonotaria citrea) and Canada warbler (Wilsonia Canadensis).
